Description

  The present invention relates to an elevator progressive safety device (Bremsfangrichrichung, progressive safety gear) comprising an elevator car and a counterweight guided and movable on a guide rail, the elevator car or the counterweight being an operating unit as defined in the independent claim It can be stopped on the guide rail by a brake unit equipped with

  A progressive safety device for elevator cars is known from EP 1 283 189. A base plate is arranged movably on a support element perpendicular to the guide rail for guiding the elevator car. On the base plate, at least one actuating lever and a brake shoe are arranged opposite thereto. When the progressive safety device is actuated, the free end of the actuating lever comes into contact with the guide rail and moves to the engagement position by a component of frictional force generated in parallel with the guide rail. In this engaged position, the guide rail is fixed between the free end of the operating lever and the brake shoe.

  The actuating lever is actuated by a slide which is rotatable about an axis and which itself can be actuated by a rope of the governor. The governor stops the rope when an overspeed occurs in the elevator car.

  By moving the elevator car relative to the stopped rope, the slide starts to rotate and moves, and the operating lever is operated.

  A disadvantage of the known device is that the progressive safety device is actuated via a governor rope. Rope vibration of the governor rope that extends over the entire height of the hoistway can cause noise in the elevator car and cause the progressive safety device to malfunction. A governor is a mechanically complex and prone device that requires space above the hoistway and in the hoistway pit. Furthermore, only one speed can be monitored.

  A progressive safety device for an elevator car is known from WO 00/39016. Instead of the governor rope, an electromagnet is provided as an actuating device. In the actuated state, the electromagnet holds the first latch lever mechanism, and the first latch lever mechanism itself holds the second latch lever at one end. The other end of the second latch lever is engaged with a groove of a spring biased pin acting on the actuating lever. At the free end of the actuating lever, there is arranged a fixed roller which is movable along the side of the wedge when actuated and is fixed with the free web of the guide rail and the wedge. When the electromagnet is switched to a non-current state, the first latch lever releases the second latch lever, and the second latch lever releases the pin that operates the actuating lever by the spring force.

A disadvantage of the known device is that, in operation, the spring must accelerate the pin and the actuating lever with a blocking roller located on the long lever of the actuating lever. This results in a long dead time until the elevator car brakes are activated. When the power supply fails, it is necessary to buffer the power supply to the electromagnet with the uninterruptible power supply to prevent malfunction. Furthermore, the safety device works only in one direction and is only suitable for operation at low speeds.
European Patent No. 1283189 International Publication No. 00/39016 Pamphlet

  The present invention begins by providing an improvement. The invention characterized in claim 1 avoids the disadvantages of the known devices and proposes a method for engaging a progressive safety device, which is easy to operate in the downward and upward travel directions and is easily reset. Provide a solution to form a safety device.

  Further advantageous developments of the invention are stated in the dependent claims.

  The advantage achieved by the present invention is mainly that the progressive safety device can be operated with few moving parts, resulting in a short response time. Since only a small mass needs to be accelerated by the actuation spring, the spring required for actuation may be small. Progressive safety devices are actuated up and down by the same parts, and braking force is generated by the movement of the elevator car. The resetting of the operating parts is done by the parts that brake the elevator car. The energy for reset comes from the traveling movement of the elevator car. Manual release of the elevator car and progressive safety device is not required.

  Progressive safety devices can be operated with small electrical energy and have sufficient driving force for operation. For example, in the event of a power failure, the capacitor is sufficient for energy storage.

  Furthermore, an advantage of the present invention is that the entire progressive safety system is located on the elevator car. Parts such as governors, governor ropes, and tension pulleys that are arranged in the machine room or elevator hoistway are not required. Progressive safety device activation and unlocking is not limited to overspeeding. Actuation can be performed at any elevator car speed or when the elevator car is stationary. For example, an operation for inspection purposes can also be performed by operating a push button.

  With a progressive safety device, a working space can be reserved, for example in the overhead space of the hoistway, and the operation can be performed when the elevator car is stationary or slow. When activated during a stop, the progressive safety device engages after moving several centimeters. To reset, the elevator car is moved in the opposite direction. The braking force in the upward direction of travel can be set by a spring arranged on the brake shoe.

  In the progressive safety device for an elevator according to the invention, the elevator car or counterweight is stopped on the guide rail by the brake unit, the actuating unit forms a frictional engagement with the guide rail and rotates by movement of the elevator car. The actuating arm has an actuating arm capable of initiating movement, and the actuating arm moves together a support portion having a brake shoe of the brake unit. The operating unit is controlled by an electrical signal that is generated, for example, when the elevator car speed deviates from a predetermined reference value.

  The present invention is described in detail below with reference to the accompanying drawings.

  FIG. 1 shows a progressive safety device 1 according to the invention with a brake unit 2 and an actuating unit 3. For example, each guide rail 5 of the elevator car is provided in the brake unit 2 arranged on a sling of the elevator car. The brake unit 2 is arranged on a base plate 4 which is held in a neutral position by a center spring 4.1 and a centering screw 4.2. Since no restraining force is generated, the base plate 4 is held movably with respect to the mounting plate 13 by bolts and elongated holes. Rail play s is set by centering screw 4.2.

  The brake unit 2 basically has a triangular rotation including a first brake shoe 6, a second brake shoe 9 and a third brake shoe 10 disposed on a base plate 4 having a first spring assembly 7. The support portion 8 of the first brake shoe 6 is disposed to face the first brake shoe 6. A first corner of the support portion 8 is rotatably disposed on the first shaft 11, and the first shaft 11 is rotatably disposed on the base plate 4. The first shaft 11 extends to the opposing brake unit 2 and operates the support portion simultaneously with the brake shoe of the brake unit 2.

  The second brake shoe 9 is disposed at the other corner, and the third brake shoe 10 is disposed at the third corner of the support portion 8. For example, when operated beyond the speed limit of the elevator car, the second brake shoe 9 engages upward and the second spring assembly 12 affects the braking operation of the elevator car or reduces the braking force. . For example, when operating in the downward direction beyond the speed limit of the elevator car, the third brake shoe 10 is engaged. Generally, there are no spring assemblies that affect elevator car braking.

The operation unit 3 basically includes an electromagnetic actuator 14 having a tightening bolt 14.1, a guide bolt 15 having a first compression spring 16, and an operation arm 17. The first compression spring 16 is a guide. It is arranged coaxially with the bolt 15. The actuator 14 can also be actuated by hydraulic, pneumatic or electric machine principles. The guide bolt 15 is connected to a swivel bearing 18 at one end and to an operating arm 17 at the other end, and the first compression spring 16 is in contact with the free bearing 18 at one end and the operating arm 17 at the other end. . The clamping bolt 14.1 of the actuator 14 releases the guide bolt 15 and the compression spring 16 moves the guide bolt 15 and the actuating arm 17 in the direction of the guide rail 5. An elongated hole 19 is formed at the free end of the operating arm 17, and a bolt-shaped follower 20 of the support 8 protrudes therein. The actuating arm 17 can move relative to the follower 20 at least twice the play s of the rail. A groove 21 is provided on the end face of the operating arm 17.

  In operation, the first compression spring 16 moves the actuating lever 17 and presses it against the guide rail 5, so that the groove 21 thereby forms a frictional engagement with the guide rail 5. When the elevator car moves upward, the actuating arm 17 moves by frictional engagement around the universal bearing 18 in the clockwise direction, and the support 8 rotates with it by the follower 20. After the second brake shoe 9 covers twice the play s of the rail, the second brake shoe 9 comes into contact with the guide rail 5 and further rotates to the stop portion 29. As a result, the first shaft 11 rotates with it, and the support rotates with the two brake shoes of the opposing brake unit. As the second brake shoe 9 rotates, the first brake shoe 6 comes into contact with the guide rail 5 and is guided by a spring force, and a necessary brake force is generated on the guide rail 5.

  In order to release the brake unit 2, the elevator car is moved in a direction opposite to the previous traveling direction. As a result, the support portion 8 is returned together with the brake shoes 9 and 10 until the contact of the second brake shoe 9 with the guide rail 5 disappears. Thereafter, as schematically shown in FIG. 4, the support portion 8 is returned to the neutral position by the spring-biased reset roller 26. The reset roller 26 rotates in the recess 25 of the cam disk 23 disposed on the first shaft 11 by the action of the force of the second compression spring 27. The neutral position of the support 8 is monitored by a sensor 28. As the sensor 28, for example, a digital comparator 28 for monitoring the position of the recess 25 is provided. The signal of the digital comparator 28 means that “the brake unit is engaged”.

  When the elevator car moves downward, the operating arm 17 rotates by frictional engagement around the universal bearing 18 in the counterclockwise direction, and the support portion 8 rotates together with the operating arm by the follower 20. After the third brake shoe 10 covers twice the rail play s, the third brake shoe 10 contacts the guide rail 5 and further rotates to the stop portion 29. The brake operation and the reset operation further proceed in the same upward direction as the elevator car traveling.

  In the last part of the rotational movement of the support 8, the actuating arm 17 is pushed back against the force of the first compression spring 16 by the reset pin 8.1. The guide bolt 15 is thereby reengaged with the clamping bolt 14.1 of the actuator 14.

  The progressive safety device 1 can be used for an elevator equipped with an elevator car and a counterweight, or a plurality of elevators that run on the elevator hoistway. The elevator car and the counterweight are guided on a guide rail and connected by a suspension means. In the case of an abnormal speed, the brake unit 2 stops on the guide rail, and the operating unit 3 puts the brake unit 2 into an operating state. The progressive safety device 1 according to the invention can be used to stop an elevator car or stop a counterweight on selectable operating criteria. The progressive safety device according to the present invention can also be used in an auto-propelled low press or beltless (no counterweight) elevator car that runs autonomously.

  FIG. 2 shows the progressive safety device 1 in cross section with details of the actuating unit 3. At its free end, the guide bolt 15 has a transversely drilled conical hole into which the cone 14.3 of the clamping bolt 14.1 is fitted. A bearing ring 18.1 is placed on the universal bearing 18 and a first compression spring 16 is placed thereon. When the cone 14.3 of the clamping bolt 14.1 is withdrawn from the hole 14.2 drilled in the transverse direction, the compression spring 16 moves the guide bolt 15 and the actuating arm 17 in the direction of the guide rail 5. With the solenoid 14.4, the tightening bolt 14.1 is retracted or the brake unit 2 is unlocked. When the solenoid 14.4 applies an electrical shock to it, the bolt body 14.5 is drawn into the solenoid 14.4, in which case the guide bolt 15 is released. At the same time, the pin 14.8 connected to the bolt body 14.5 begins to move against the force of the third compression spring 14.6 opening the safety contact 14.7, and the interrupt signal of the safety contact 14.7 Informs you that the brake unit has been unlocked. When the electrical signal to the solenoid 14.4 is lost again, the clamping bolt 14.1 is moved towards the guide bolt 15 by the third compression spring 14.6 until the cone 14.3 is placed against the guide bolt. After the guide bolt 15 has returned to its initial position, it is only possible to move the cone 14.3 in the hole 14.2 opened in the transverse direction.

  FIG. 3 shows the progressive safety device 1 with a reset mechanism for the actuating arm 17 or the guide bolt 15. The actuating arm 17 is shown cut open. A pressure plate 17.2 that is rotatable around the second shaft 17.1 is held in a neutral position by a leaf spring 17.3. The second shaft 17.1 and the leaf spring 17.3 are arranged on the operating arm 17.

  5 to 8 sequentially show the engagement operation of the brake unit and the reset operation of the operation unit 3. FIG. 5 shows the brake unit 2 in the neutral position and the locked position. The cone 14.3 of the clamping bolt 14.1 holds the guide bolt 15 fixedly in a hole 14.2 which opens in the transverse direction. The pressure plate 17.2 is in the middle of the recess 25 by the leaf spring 17.3 and the support 8 by the reset roller 26. FIG. 6 shows the position of the actuating arm 17 after the cone 14.3 has been pulled out of the transversely opening hole 14.2. The first compression spring 16 guides the groove 21 of the operating arm 17 onto the guide rail 5. When the elevator car does not move, the brake unit 2 remains in the unlocked state shown. When the elevator car moves downward, the operating arm 17 rotates counterclockwise around the universal bearing 18 and rotates the support 8 around the first shaft 11 by the follower 20 as shown in FIG. . Due to the rotation of the support part, the reset pin 8.1 hits the pressure plate 17.2 and pushes the actuating arm 17 and the guide bolt 15 toward the universal bearing 18, and the cone 14.3 of the clamping bolt 14.1 Glide on the top. FIG. 8 shows the final position of the support portion 8 in a state where the two brake shoes 9 are in contact with the stop portion 22 and the third brake shoe 10 is engaged with the guide rail 5. The first brake shoe 6 is also engaged with the guide rail 5 and generates a braking force in conjunction with the third brake shoe 10. The reset pin 8.1 pushes back the actuating arm 17 and the guide bolt 15 until the cone 14.3 slides into the transversely open hole 14.2. As shown in FIG. 8, the brake unit 2 is locked again, but is in an engaged state. When the elevator car moves upward (opposite), the support portion 8 rotates in the clockwise direction, and after the third brake shoe 10 does not contact the guide rail 5, the reset roll 26 rotates in the recess 25. Again, in the middle of the neutral position. At the same time, the pressure plate 17.2 is returned to the initial position by the leaf spring 17.3.
